The gut microbiota are microorganisms or bacteria that reside in our intestinal tract. Everyone has approximately 100 trillion microorganisms within their digestive system! Each person has a unique collection and assortment of these bacteria which are unique as our fingerprints. These gut bacteria play a fundamental role in shaping our metabolism, neuronal, and hormonal (endocrine) systems.
Microorganisms also impact our immune function and if dysfunctional, can contribute to problems such as obesity, diabetes, inflammatory bowel disease or depression. There are many research articles that show that the administration of certain strains of gut bacteria to rodents, results in decreased anxiety and depression.
